Replace the '100' in your key file with '101'. Basically, you've already used the '100' nonce, which has to be a continually increasing number. If you use it twice, then you get this error.
Many thanks area - sorry for being so clueless on this!
All more or less running well now. I did run into another problem (detailed below) but suspect it's just a server issue. Would be great if it could fail gracefully (i.e. retry) rather than quitting, but it's not a huge issue.
